Description

While running OpenSolaris 2008.05 on VirtualBox on top of MacOS or Solaris Nevada b87, "kstat -m battery" doesn't report laptop battery information properly. It appears that the SBST (Smart Battery Table) from the ACPI of the host is not being reported to the guest OS.

This information is used by utilities such as PowerTop to display battery information to the user when the system is running on battery power.
